Abstract (en)
[origin: EP0690346A1] The device drives and controls the position of a film (7), with a device for printing on the film using a laser beam (F). The displacements of the laser beam are controlled by an optical x-y deflection system (S) under the control of a computer. The system includes a motor (M) controlled by the computer and making the film run continuously, but with interruptions for printing the film. A toothed device is coupled to the motor, and faults in the centricity of the drive are detected, with appropriate compensation being applied to the laser beam. <IMAGE>
